MOSQUITO-CURTAIN.

Specification of Letters Patent No. 11,764, dated October 3, 1854.

To all whom, it may concern:

Be it known that I, BENJAMIN B. VEH- STER, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in the Application of h/Iosquito-Curtains to a Window; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawing, letters, figures, and references thereof.

Of the said drawings, Figure 1, represents an inside view of a window having a mosquito curtain applied to its lower sash in accordance with my invention, the lower sash being partially elevated in order to more clearly exhibit the said curtain. Fig. 2, is a vertical, central, and transverse section of the same.

In the drawings, A, represents a window frame provided with two sashes, B, C.

D is a curtain roller arranged across the lower girth of the window frame and below the lower sash and supported in bearings seen at E, F, in Fig. 1, also in Fig. 3, which eX- hibits a horizontal section of it and its bearings. There is rolled around and attached to this roller a lace, open, or other suitable curtain, G, one end of which is aflixed to the roller, while the other end is fastened directly to the lower bar of the lower sash or what is better to a movable bar, H, so attached to the sash as to admit of being easily removed therefrom, or aflixed thereto, as occasion may require.

The curtain roller is provided with a coiling or winding up spring, a, applied to one end of a box or case, 0, as seen in Figs. 1, and 3.

When the sash of the window is raised it will elevate and unwind the mosquito curtain so as to cover the open space of the window in such manner as not only to allow air to circulate through the same, but to prevent the ingress of mosquitoes or other insects. Alike curtain may be applied to the upper sash if necessary.

I do not claim the combining a mosquito curtain with a window, but

What I do claim is To so continue it therewith, that it may be attached to the sash of the window and a roller applied to the window frame and be operated by said sash, and so as to close the opening produced by the raising of said sash, substantially as above set forth, the said curtain being wound upon the roller by the action of a spring or its equivalent when the sash is in the act of being closed.

In testimony whereof, I have hereunto set my signature this twenty-eighth day of June, A. D. 1854.

BENJAMIN B. IVEBSTER.
